My Problem...For a school project I have to build a game using construct2, I finished the task weeks before anyone else so I had time to add 'finishing touches' to the game, during this it appears that I have 'unlinked' the event sheet from the layout. When I click play I can only see my menu screen and none of the buttons or anything works. After hours of trying to figure this out I'm in a situation where I need this handed in within the next few days.

Check in your layout properties window (on the left side when you click on a layout), you will see Event sheet with (none) next to it. Click on (none) and you can link any event sheet to it. If you need to link 2 or more, make an event sheet for your layout and include the event sheets to that one.

If you can space out your link ( l i k e t h i s ) so someone can get the whole thing - we can download it and check it out for you.

It sounds like what @SimoneT said though... you've somehow unlinked your event sheet to the layout, or something. If this is a school project then I assume your teacher knows about Construct 2 and how to use it... maybe he/she will be able to help you solve the problem also if nobody else here can.
